AT_arc125_c [ARC125C] LIS to Original Sequence 题解

题目传送门 前置知识 贪心 | 构造 解法 对于任意一个未加入序列 \(P\) 的数 \(x<A_{i}(1 \le i \le k-1)\),如果其放在了 \(A_{i}\) 的前面,会导致最长上升子序列长度加一,从而不符合题目要求。因此我们需要把 \(x\) 放在 \(A_{i}\) 后面,同理 ......

ARC169 前言 学校晚饭后不让来机房,时间卡的很死。基本赶不上赛时 AtCoder,更不能谈 codeforces 了。这就导致到现在一场 ARC 没参加过。 于是今天 VP 了一下,A题很水十分钟碾过去了,B题先想到了一个假贪心,答题思路不变稍微改改改成 dp 就可以了。C 题写的比B还快,比 ......

分析 注意到本题在放完盘子之后就是一个简单的 Nim 问题,所以考虑每个背包会放到哪个盘子。由于放完盘后谁执先手与 \(n\) 的奇偶性有关,于是分类讨论。 如果 \(n\) 是奇数,放完后后手先取硬币,他肯定会尽量让异或和不为 \(0\)(Nim 的玩法),那么他有一个必胜策略:不管先手取哪个背包 ......
